IMPROVEMENT IN SHUTTER-WORKERS.

Specification forming part of Letters Patent No. 164.463, dated J une15,1875 application filed April 3, 1875.

OAsE B.

To all whom it may concern:

Be it known that I, WILLIAM M. LANPHERE, of WVaterloo, in the county ofBlack Hawk and State of Iowa, have invented a new and Improved BlindOpener and Fastener, of which the following is a specification:

The invention consists in the provision of a hinged angle-plate, whichis carried by a pushrod, employed for starting or dislodging the shutterwhen bound by frost or any slight obstruction, said plate serving tofasten the shutter, when closed, by engaging with its lower edge.

Figure 1 is a sectional elevation of a window-frame and side elevationof a blind, showing the operating-gears and the starter andfastening-plate. Fig. 2 is a horizontal section taken on the line y y ofFig. l, and Fig. 3 is a detail section taken on the line 2 z of Fig. 1.

Similar letters of reference indicate correspondin g parts.

A is the window-blind; B the side, and O the bottom, portions of thewindow-frame E, the gear-wheels for opening and closing the blinds; F,the shaft for turning the wheels; G, the locking-slide for fastening theblind open or shut by one of the wheels; H, the rod working it M, thestarter foropening the blind; J, the bar for working the starter, and Kthe hinged fastening-plate, combined with the starter-slide for beingworked by it to fasten the blind shut from the inside, so that it cannotbe opened from the outside. This fastening-plate consists of a littleangle-plate hinged to the end of the starter-slide, in combination withthe incline L, to let it fall when the blind opens for the blind to passover it, and to swing it up behind the blind when it closes. The rod Mof the starter will be fastened inside of the room by a catch, N, or anyapproved means. I

Having thus described my invention, I claim as new and desire to secureby Letters Patent The combination of the hinged angle-plate K and rod Nwith the shutter A and casing 13, as and for the purpose set forth.
